(54) Disc and hub assembly for electromagnetic clutch in a compressor


(57) The present invention relates to a disc and hub assembly for an electromagnetic clutch of a compressor. The assembly comprises: a disc (120) adapted to be attracted to or separated from a friction surface of a pulley under the action of an electromagnetic coil; a hub (110) coupled to a driving shaft of the compressor, the hub penetrating the disc (120) and having a flange (112) formed on its outer peripheral surface; a plate spring (130) which includes a plate portion (131) coupled to the top surface of the disc (120), a number of leaf spring portions (135) obliquely extending inwardly from the plate portion (131) to be coupled to the flange (112) of the hub (110) and having ends (137) which are bent toward the disc (120), and dampers (160) coupled to the ends of the leaf spring portions (135); and shock-absorbing means (140) interposed between the disc (120) and the plate portion (131) to reduce noise and impact during on/off of the clutch.
